An idea

Water

The traveler that never runs out

The water on Earth is never new. It has been a cloud, a river, an ocean, and rain, over and over, for billions of years. The water in your glass tonight has been somewhere astonishing before.

Given enough time, water also rearranges the world. It carves rooms out of solid stone, freezes into six-armed stars, and climbs invisibly into the sky so the whole journey can begin again.
